chop2816-default.mp3Interpretation sequence sampled from the prior
chop2816-calm-vector.mp3Same as left, but the interpretation sequence has been offset. Notice that it generates a much calmer and shorter articulation.
Ragtime
ragtime-default.mp3Interpretation sequence sampled from the prior
ragtime-calm-vector.mp3Same song as the left, but adjusted the interpretation sequence the same way as above. Notice that here the playing becomes calmer and softer. This shows that the property of interpretation vector remains consistent between pieces.

Visualizing the piano-roll as interpretation vector is changed
Here, we can see that the articulation changes (as well as dynamics and the tempo) as we change the interpretation vector. The audio here plays the bottom two piano-rolls, first the left followed by the right. You can hear subtle nuances in the articulation as well as the tempo
